SCSI misc on 20221222

Browse source 
Mostly small bug fixes and small updates.  The only things of note is
 a qla2xxx fix for crash on hotplug and timeout and the addition of a
 user exposed abstraction layer for persistent reservation error return
 handling (which necessitates the conversion of nvme.c as well as
 SCSI).
